Default Riotoro Builder series starts to show up (probably) with DC-DC

For only 40 euro incl VAT for the 500W version and 50 euro incl VAT for the 600W version. But it doesn't comes with 80PLUS Bronze, just 80PLUS standard. But if it has DC-DC the efficiency is most likely only lower than 82% far under the 20% load and with 100% load. DC-DC units like this one mostly go the an efficiency of 87% around 50%. I expect DC-DC because both can deliver al their power on the 12V, typical for a DC-DC unit. Of course there is also a change it doesn't has DC-DC, but uses a different method to get individual voltage regulation.

First "copying" EVGA with Enigma "G2" and now Corsair with the old "CX Builder Series"

If DC-DC, quite a good price!

And what if this PSU has a fake label and in the reality is just a group regulated design?
Just a 80 plus is too little for what we need a respected PSU IMO.

I don't believe that Riotoro does that.

"Never attribute to malice that which is adequately explained by stupidity."

Also they can mean 3,3V and +5V/+12V is still group regulated...

But lets wait and see.


The cheapest unit with "real" DC-DC is this one:

Why? Because is new on the market? If EVGA did something like that why Riotoro won't?

Yes but at that price there also the non "+" one wich makes confusion a little bit. If you take the non "+" one you take a not so good platform.
And if you take a look at the user reviews on Geizhals will see that has more negative review than the positive ones, and this reflects the poor quality of that PSU imo.

Performance A and A+ are two totally different units, have nothing to do with eah other...

And the A is EOL anyway...

Yes, because those people don't know shit and rate PSU if they die in the first week or not.
Most of those negative reviews were what people in the industry call "dead on arrival", wich means that the unit eiter arrived dead or dies within a short period of time.


That happens with every manufacturer out there. That's "normal"...
And with cheaper ones like the Performance A+ it might happen a bit more than for example Corsair but that's also why they are so cheap!

We are talking about 8 for the ~400W and a whopping 12 more for the ~500W Version. 55 for the be quiet Pure Power 10 vs. 42 for the Performance A+...

People are just to ignorant for the "you get what you pay for" principle...

Got some quick shots.

1st one is the massive heatsink on the PFC bridge.

2nd is an overhead shot. No idea who the OEM is right now.

3rd is the undersized bulk cap.

4th is the D2D card.

5th shows a proper Weltrend supervisor IC.

Feels like Sirfa.
At least DC-DC module looks a bit like that and the heatsinks and also:
